NBSN95 Waterproof Wireless NB-IoT Sensor Node
NBSN95 works with NB-IoT sim cards (global coverage).
NBSN95 is a Long Range LPWAN NB-IoT Sensor Node. It is designed for outdoor data logging and powered by 8500mAh Li/SOCl2 battery for long term use and secure data transmission. System Integrator can use NBSN95A to rapidly deploy NB-IoT sensor node for their IoT solution. NBSN95 is easy to program, create and connect things everywhere.
NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage.
NBSN95 is an open-source project. It is based on the STM32L072CZT6 ultra-low-power ARM® Cortex®-M0+ microcontroller. Developers can get completely software and hardware design files and adapter for their projects.
